I just received an Atten 858D+ hot air rework station direct from China. When I plugged it in and switched on it was completely dead - no display or any activity. On taking the front panel off I found that the power input socket had been mis-wired and mains active was tied directly to the exposed metallic parts of the heat gun.
This is a potential killer - no pun intended. Please if you have purchased but not received one of these items check the mains wiring before switching on. Even if you have one that appears to be functioning ok it would be best to have a look whether it has more insidious faults such as neutral to earth or active-neutral transposed.
For what it's worth the serial number of my unit is 1042111302610.
man that is bad
surprised it did have any sort of qa test
What's a qa test?

I found, indeed, that the casing was not grounded anywhere! Same problem with paint all over the place.
Also, the mains plug didn't comply with BS1363 (shrouded earth pin!) and contained 13A fuse, highly inappropriate for the very thin bundle of strands in the cable...
I changed cables, scraped off paint all of those spots, and added a ground tab using the transformer's connection to the casing, directly to the earth pin on the inlet.
Initial looking at the circuit board suggests, also, that little attention is paid to isolating low and high voltages anywhere. Had anybody noticed this?
